Not sure what the term ACID RAP means, but the creation of Nosaj Thing and Chance The Rapper is pretty much one of the raddest hip hop tracks I've heard in a long, long time... and yes, the song is almost a year old, but...
Chilled, kinda trappy and carrying the flow of awesomeness, "Paranoia" is one of the tracks which the guys joined forces on for a series called Songs From Scratch which aimed to put together various artists and... make them create music from scratch? The compilation includes artists like Jeremih, Danny Brown, Jacques Greene and Shlohmo. Yep, good stuff!
